Here's a trick I use often. Any woodworker (as well as metal worker) should own 1-2-3 steel blocks. They are inexpensive, very accurate to just a few TEN THOUSANDTHS (1/10,000) of an inch on all sides. These can then be used as accurate spacers and add extra height too. I use them on the table saw when I need very accurate on inch cuts since you can make any combination of distances the more blocks you have. I think the set of 4 blocks I bought were $29 from ebay. I plan to add some 2-4-6 blocks soon as well, those run around $65 or more for a set of 2.

You can use 1-2-3 or 2-4-6 blocks to set a table saw blade perfectly square, jointer fence dead square. A lot more uses for them in the wood shop than most realize.

My concern is that it's only 3/4" thick. If you're working with 3/4" material, you have to lower the rail to calibrate it, but in raising the rail to accommodate the 3/4" (or 18mm, or 19mm, or whatever) material, the act of releasing the rail clamp and resetting it to a different height is likely to induce an error, however minor. If Woodpeckers had chosen to make it thicker, say 1-1/8" (like the original MFT square), one could zero the rail and not be concerned about errors induced by raising and/or lowering the rail once it's been zeroed. This rather makes the argument about "the '.0085" is .0085 degrees per foot'" insignificant.

Thanks for taking the time to stop by the forum today to answer questions from the forum members and potential buyers of your well-designed MFT squaring solution. It's fantastic for us to have insight and information directly from the product's designer.

Hey Everyone, I just want to clear things up a bit... This is Ed from Woodpeckers and this is my tool.

First: The accuracy statement.This is for degrees, so the ".0085" is .0085 degrees per foot.

As others have asked, what does this really mean? Taken literally, 0.0085deg/foot * 1.5' = 0.0128deg. But degrees/foot is really strange, as it would imply some kind of spiral (increasing curvature with distance).

I think the statement .0085 degrees per foot is just a misnomer on Woodpeckers part. If you take a look at the advertised perpendicularity specifications for other Woodpeckers products, you’ll see they reference .0085 degrees without adding the “ per foot” moniker.

Perhaps.

Could be related to the inspection method: deviation of up to 0.0085 degrees as measured at 12 inches or across 12 inches.

Hi Ed, don't know if the tool design is "locked" at this point, but I have a suggestion. As several people have pointed out, it would be nice if there was a way to have the square be more than 3/4" thick. This of course was a feature of the Woodpecker MFT square - which was much more expensive than this tool. How about some sort of phenolic or aluminum bushings/dogs that could be fit into the holes, thus raising it off the work surface? This could be an optional add-on.

Regardless, I'll be buying one of these tools. It seems to have a lot of uses beyond setting up the MFT. Thanks for creating a nice tool.

Hey guys... long time reader, first time poster. Please forgive me if this was discussed already, but I'm looking for some input before pulling the trigger on one of these knowing the deadline is today.

Instead of buying this one trick pony if only using to setup the MFT. .wouldn't it be better to buy a parallel TSO guide rail square? Attach to your rail, butt up against the fence and adjust. Sure it's more expensive but also extremely more useful.

There are plenty of squares out there. While the Insta-RailSquare does a great job at letting you get perpendicular cuts quickly and easily, it's a purpose built tool. It could be used for MFT alignment especially when used with the optional Insta dogs since you could use the MFT hole grid as a reference for the fence and rail. For the best deal, you can buy the Insta-RailSquare and dogs as a kit to save about $10.

The Woodpeckers OTT MFT square is going to be a thicker and longer square to give a more surface to reference off of. It's not a one-trick pony since it could be used for any squaring task, although there are features that help with MFT squaring.

The Woodpeckers 1281 could also definitely be used for squaring an MFT and includes a scale, unlike the OneTime Tool MFT Square.

I'm sure some of the forum members will give their insights and opinions.
